The invention relates to an arrangement comprising at least one electronic component and a cooling body associated therewith. A support physically interposed between the electronic component and the cooling body and the support has at least one layer with at least one material of an electric strength of at least 10 kV/mm and a thermal conductivity of at least 5 W/mK. At least one recess and/or at least one protruding element is arranged in and/or on the layer of the support, and is configured in such a manner that it extends, along the surface of the layer of the support, through preferably all electrically possible pathways between the electronic component and the cooling body as compared to the condition of the layer of the support without the recess and/or without the protruding element.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An arrangement comprising: an electronic component; a cooling body associated with said electronic component; and a support interposed between said electronic component and said cooling body, said support having a layer formed of a material having a dielectric strength of at least 10 kV/mm and a specific thermal conductivity of at least 5 W/mK, said layer of said support having: a top surface supporting said electronic component; a circumferential surface adjacent to said top surface and oriented transversely with respect to said top surface; and a formation at said circumferential surface, said formation being configured to extend along said circumferential surface of said layer so as to lengthen electrically possible pathways between said electronic component and said cooling body as compared with a condition of the layer without the formation, said formation comprising at least one of a recess in said circumferential surface and a protruding element on said circumferential surface.
2. The arrangement of claim 1 , wherein said formation is configured to extend along said circumferential surface of said layer so as to lengthen all electrically possible pathways between said electronic component and said cooling body.
3. The arrangement of claim 1 , wherein said formation is configured to extend along an entirety of said circumferential surface so as to encircle said support.
4. The arrangement of claim 1 , wherein said formation comprises said recess having a groove-shaped or a trench-shaped configuration.
5. The arrangement of claim 1 , wherein said formation comprises said protruding element having a wall-shaped configuration.
6. The arrangement of claim 1 , wherein said formation is configured so as to lengthen the electrically possible pathways between said electronic component and said cooling body by at least 30%.
7. The arrangement of claim 1 , wherein said formation is configured so as to lengthen the electrically possible pathways between said electronic component and said cooling body by at least 100%.
8. The arrangement of claim 1 , wherein said formation comprises said protruding element, at least two selected from a group consisting of said support, said layer of said support, and said protruding element being made from the same material.
9. The arrangement of claim 1 , wherein said formation comprises said protruding element, at least two selected from a group consisting of said support, said layer of said support, and said protruding element having a one-piece construction.
10. The arrangement of claim 1 , wherein said formation comprises said protruding element, at least one selected from a group consisting of said support, said layer of said support, and said protruding element being constructed from interconnected individual portions.
11. The arrangement of claim 1 , wherein a material of said layer of said support comprises one of an aluminium nitride or an aluminium oxide.
12. The arrangement of claim 1 , wherein said electronic component comprises a high-voltage component for operating voltages of between 5 kV and 400 kV.
13. The arrangement of claim 1 , wherein said electronic component is configured such that power losses of said electronic component are between 10 W and 10 kW and are to be dissipated as heat.
14. The arrangement of claim 1 , wherein said electronic component and said support having said layer and said formation are embedded in an electrically insulating medium.
15. The arrangement of claim 14 , wherein said insulating medium is one of an insulating oil, an insulating gas, or a casting resin.
16. The arrangement of claim 1 , wherein one of said electronic component or said support having said layer and said formation is embedded in an electrically insulating medium.
17. The arrangement of claim 16 , wherein said insulating medium is one of an insulating oil, an insulating gas, or a casting resin.
18. The arrangement of claim 1 , wherein said support has a substantially parallelepipedic configuration.
19. The arrangement of claim 1 , wherein said cooling body has cooling ribs.
20. The arrangement of claim 1 , wherein said cooling body comprises aluminium or the same material as said layer of said support.
21. The arrangement of claim 1 , further comprising electrical contacts for electrically connecting said electronic component, said electrical contacts being arranged outside said support, said electrical contacts comprising at least one of a contacting member, an electrical feed line, and a discharge line.
22. The arrangement of claim 1 , wherein said layer of said support has at least one of a minimum edge length of 100 mm and a minimum thickness of 2 mm.
23. The arrangement of claim 1 , wherein said electronic component comprises one of a plurality of electronic components arranged on said top surface of said layer of said support.
24. The arrangement of claim 1 , wherein said electronic component comprises one of at least three electronic components arranged on said top surface of said layer of said support.
25. A layer suitable for an arrangement of claim 1 .
26. A support suitable for an arrangement of claim 1 .
27. An arrangement comprising: a cooling body to be associated with an electronic component; and a support to be interposed between the electronic component and said cooling body, said support having a layer formed of a material having a dielectric strength of at least 10 kV/mm and a specific thermal conductivity of at least 5 W/mK, said layer of said support having: a top surface for supporting the electronic component; a circumferential surface adjacent to said top surface and oriented transversely with respect to said top surface; and a formation at said circumferential surface, said formation being configured to extend along said circumferential surface of said layer so as to lengthen electrically possible pathways between the electronic component and said cooling body as compared with a condition of the layer without the formation, said formation comprising at least one of a recess in said circumferential surface and a protruding element on said circumferential surface.
